CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefits of U.S. provisional patent application No. 60/780,344 filed Mar. 9, 2006, which is hereby incorporated by reference.

TECHNICAL FIELD

The present invention relates to a sporting article with an adjustable weight configuration. More specifically, the present invention relates to a golf club head with an adjustable weight configuration.

BACKGROUND

When practicing sports, the weight balance of a sporting article may have an impact on the performance of the user, be the sporting article be a golf club, racket, a hockey stick, a ski, etc.

For example, when swinging a golf club at a golf ball, some golfers have a swing such that the heel portion of the golf club head tends to move faster than the toe portion. This results in the heel portion arriving ahead of the toe portion at impact, causing the impact surface to be misoriented. This is what is commonly referred to as a “slice”. Conversely, some golfers have a swing such that the toe portion of the golf club head tends to move faster than the heel portion. This results in the toe portion arriving ahead of the heel portion at impact, causing the impact surface to be misoriented. This is what is commonly referred to as a “hook”.

Thus, golf club heads are configured in a variety of geometries in order to move the weight of the golf club head to points that enhance stability, i.e. more weight at either the heel or toe portion slows down that portion during the swing. These points differ from one model of golf club to another.

While common golf clubs operate satisfactorily, most of the weighted golf club heads suffer from the limitation that their weight distribution cannot be readily altered to customize the golf club to the needs of a particular golfer. Other sporting articles suffer from

DETAILED DESCRIPTION

Generally stated, the illustrative embodiments of the present invention provide sporting articles for users of all calibers; from amateur to professional. The present invention allows the user to adjust the weight distribution of the sporting article in order to customize it to his or her particular needs. Moveable weight members of various weight values may be positioned along a guide in various configurations, for example, transversally, longitudinally and/or diagonally, at various positions and angles on the sporting article so that the user may properly adjust the weight distribution of the sporting article to perform a desired shot or improve maneuverability.

Referring to FIGS. 1 and 2, there is shown an example of a sporting article in the form of a golf club head 100 having a hosel 11, to connect the golf club head 100 to a golf club shaft (not shown), a crown portion 12, a sole portion 13, a toe portion 14, a heel portion 15, a face portion 16 with an impact surface 17 and a rear portion 16. In the illustrated embodiment, the golf club head 100 includes two moveable weight members 40 and 50, which may be positioned in various configurations along transversal 22 and longitudinal 24 guide sections. It is to be understood that in alternative embodiments the number of moveable weight members may vary as well as the number of transversal and longitudinal guide sections, and may also include diagonal guide sections.

Furthermore, in this particular example the illustrated golf club head 100 is that of a driver. However, it is to be understood that the adjustable weight configuration may be applied to any other type of golf club head such as, for example, irons, wedges (pitching (pw), gap (gw), sand (sw), lobe (lw)) or a putter, made of whatever type of material.

The first moveable weight member 40 is generally displaced along the transversal guide section 22, which runs on the rear portion 18 of the golf club head 100 from its toe portion 14 to its heel portion 15, while the second moveable weight member 50 is generally displaced along the longitudinal guide section 24, which runs on the rear portion 18 of the golf club head 100 from its crown portion 12 to its sole portion 13. It is to be understood, however, that both moveable weight members 40 and 50 may be displaced along either or both the transversal guide section 22 and the longitudinal guide section 24.

The moveable weight members 40 and 50 typically weigh between 0.2 g and 1.0 g. However, it is to be understood that the weight value of the moveable weight members 40, 50 are given as examples only; other weight values may be used depending on the desired weight distribution, the type of club, gender and size of the golfer, etc. It is further to be understood that the weight values may also vary depending on the type of sporting article and its intended use.

Referring to FIGS. 3A and 3B, there is shown a cross sectional view of the interaction between the first moveable weight member 40 and the transversal guide section 22. It is to be understood that the first moveable weight member 40 may similarly interact with the longitudinal guide section 24 and that the second moveable weight member 50 may similarly interact with either or both of the transversal 22 and longitudinal 24 guide sections.

The first moveable weight member 40 includes an external element 40 a, an intermediate element in the form of a locking element 41, which includes a head portion 43, a threaded body 45 and a blocking portion 47, and an internal element 49. The threaded body 45 operatively engages the internal element 49, which has a complementary thread pattern. The blocking portion 47 ensuring that the internal element 49 remains operatively connected to the locking element 41.

The first moveable weight member 40 may be engaged to the golf club head 100 by inserting the internal element 49 into the transversal guide section 22, which forms a channel within the golf club head 100, through an opening 26 which is located near the heel portion 15, the locking element 41 protruding from a slot 22 a in the transversal guide section 22 such that the external element 40 a rests on the outer surface 10 of the golf club head 100. It is to be understood that the opening 26 may be located at the toe portion 14, along the longitudinal guide section 24 or may be absent altogether in an alternative embodiment were the moveable weight members 40 and 50 are not removable.

Although not illustrated, it is to be understood that the second moveable weight member 50 may be described in a similar fashion as the first moveable weight member 40. Furthermore, the second moveable weight member 50 may be engaged to the transversal 22 and longitudinal 24 guide sections in a fashion similar to the first moveable weight member 40.

Locking

Rotating the head portion 43 of the locking element 41 in a first direction results in the external element 40 a and the internal element 49 moving towards each other. The size of the external 40 a and internal 49 elements being greater than the slot 22 a of the transversal guide section 22, the external 40 a and internal 49 elements respectively frictionally abut the outer surface 10 of the golf club head 100 and part of the internal surface 22 b of the transversal guide section 22, thereby locking the first moveable weight member 40 at a given position along the transversal guide section 22, as best seen in FIG. 3B.

Advantageously, the geometry of the internal element 49 may be such as to be complementary to the geometry of the transversal guide section 22 so as to maximize the contact between the internal element 49 and part of the internal surface 22 b of the transversal guide section 22.

Unlocking

Rotating the head portion 43 of the locking element 41 in a second opposite direction results in the external element 40 a and the internal element 49 moving away from each other, thus unlocking the first moveable weight member 40 and allowing for a space 19 to be created between the external element 40 a and the outer surface 10 of the golf club head 100 so that the first moveable weight member 40 may be moved along the transversal guide section 22, as best seen in FIG. 3A. As previously mentioned, the blocking portion 47 ensures that in an unlocked position the internal element 49 remains operatively connected to the locking element 41.

FIGS. 4A, 4B, 5A and 5B show alternative embodiments of the internal element 49′, 49″ and corresponding transversal guide section 22′, 22″ having complimentary geometries. It is to be understood that other geometries may be used as well.

It is also to be understood that other locking means may be used in order to secure the moveable weight member 40 in a desired position and to release it in order to modify the weight configuration of the sporting article.

Although the above description makes reference to the transversal guide section 22, it is further to be understood that it may similarly apply to the longitudinal guide section 24 (or even a diagonal guide section in an alternative embodiment).

Referring to FIGS. 2 and 6, the transversal 22 and longitudinal 24 guide sections may be of various length. For example, in the illustrated embodiment the transversal guide section 22 may be of a length such that the first moveable weight member 40 may have a range of possible positions from line 62, at the heel portion 15, to line 64, at the toe portion 14, of about 110° along the rear portion 18. The extreme positions of the first moveable weight member 40 are identified by numerals 40′ and 40″. It is to be understood that the range of possible positions may be other than 110° , for example 120° if we use positions from line 62′ to line 64.

The moveable weight members 40 and 50 may also include transversal and/or longitudinal position indicators. In the illustrated embodiment the first moveable weight member 40 includes a transversal 42 and longitudinal 44 position indicator while the second moveable weight member 50 includes a longitudinal position indicator 34. Complementary transversal 32 and longitudinal 34 position markers may also be provided on the golf club head 100 so that a golfer may remember the position of the moveable weight members 40 and 50 in a desired weight configuration. Furthermore, the user may wish to use various weight configurations depending on the desired effect or shot.

It is to be understood that in the case of alternative embodiments having diagonal guide sections, the moveable weight members 40 and 50 may also include diagonal position indicators (not shown).

Referring now to FIGS. 7 and 8, there are shown two examples of weight configurations. In particular, FIG. 8 shows a configuration with only the first moveable weight member 40 present, which is positioned in the longitudinal guide section 24, thus the presence of the longitudinal indicator 44.
